Looking at the predictions below, Breaking Dawn - Part 1 is expected to take in somewhere between $148 to $150 million over the weekend. For comparison, the last Twilight Saga movie, Eclipse, had a weekend opening of $65 million last year. The sequel is expected to eclipse that amount by more than two times. The bad news? There will be only one more movie left in this series.

While Breaking Dawn is expected to take the lion's share of the box office, this doesn't mean there won't be any scrapes left over for the other movies. Happy Feet Two, is expected to make somewhere between $36 to $43 million. The predictions are within the $41.5 million opening the first movie had back in 2006. That's not too shabby, considering the first Happy Feet went on to make nearly $200 million domestically.

Immortals, the winner of last week's box office, is expected to come in third with a take of somewhere between $13 to $14 million. It's easy taking on gods and crazy kings, but vampires, werewolves and penguins are in a whole different league.
